Strip pixel detector

Abstract

Disclosed herein is a detector, comprising: a plurality of strip pixels, wherein each of the strip pixel is configured to count numbers of radiation photons incident thereon whose energy falls in a plurality of bins, within a period of time.

What is claimed is: 
     
         1 . A detector, comprising:
 a plurality of strip pixels, wherein each of the strip pixels is configured to count numbers of radiation photons incident thereon whose energy falls in a plurality of bins, within a period of time;   wherein the detector is configured to add the numbers of radiation photons for the bins of the same energy range counted by all the strip pixels.   
     
     
         2 . The detector of  claim 1 , wherein the strip pixels are arranged in an array. 
     
     
         3 . The detector of  claim 1 , wherein the strip pixels are configured to receive radiation photons from a sidewall of an absorption layer of the detector. 
     
     
         4 . The detector of  claim 1 , wherein each of the strip pixels comprises an analog-to-digital converter (ADC) configured to digitize an analog signal representing the energy of an incident radiation photon into a digital signal. 
     
     
         5 . The detector of  claim 1 , wherein the strip pixels are configured to operate in parallel. 
     
     
         6 . A system comprising the detector of  claim 1 , and a radiation source, wherein the system is configured to perform radiation radiography on human chest or abdomen. 
     
     
         7 . A system comprising the detector of  claim 1 , and a radiation source, wherein the system is configured to perform radiation radiography on human teeth. 
     
     
         8 . A cargo scanning or non-intrusive inspection (NII) system, comprising the detector of  claim 1 , and a radiation source, wherein the cargo scanning or non-intrusive inspection (NII) system is configured to identify elements by energy dispersive analysis using radiation transmitted through an object inspected. 
     
     
         9 . A cargo scanning or non-intrusive inspection (NII) system, comprising the detector of  claim 1 , and a high-energy X-ray source, or gamma ray source, wherein the cargo scanning or non-intrusive inspection (NII) system is configured to identify elements by energy dispersive analysis using backscattered radiation. 
     
     
         10 . A full-body scanner system comprising the detector of  claim 1 , and a radiation source, wherein the full-body scanner is configured to identify elements.
